Prevailing prayer is not so much prayer that knocks at the gates of heaven and extorts an answer from an unwilling God,as the prayer which, having received the answer and promise, carries it forth against the gates of the enemy and beats them down, as the walls of Jericho fell [at] the tramp and shout of Israel's believing hosts....It is faith putting its hand on the omnipotence of God and using it it in fellowship with our own omnipotent Head until we see His name prevail against all that oppose His will.
